To all whom it may concern:

Be it known that I, FRANCIS E. BUx'roN, a citizen of the United States, residing in the city of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Journal-Bea rings.

My present invention has special reference to wear compensating bearings including lubricating and locking means. The object broadly stated is to perfect and secure the much desired realization of radial wearcompensation, in the most simple manner, and to also provide a construction to greatly reduce the initial cost of bearings in general,

Specifically stated my invention relates to the improvement of the bearing-sleeve element, which I sim lify by a series of removable grids mounted on a tubular like bearing lining, having a series of intermediate weakened portions disposed thereon.

My intention also relates to the mechanism surrounding the bearing-sleeve, for rcliably supporting and maintaining the proper inner diameter of the bearing for exact alinement. Another feature of my invention relates to the improved mechanism for holding a proper head of oil, and distribating the same throughout the bearing. And still another feature of the invention consists on the mechanism for securely locking and releasing the bearing.

In the drawings and specification. other features will be brought vout and` explained. As shown in the drawings, Figure 1 is a side elevation of the bearing, certain parts thereof being shown in central section, to illustrate the bearing rotor mechanism. Fig. 2 is a front end elevation ofthe same, certain parts being broken away to show the oil-ring portions and lower part of the chamber. Fig. 3 is an end elevation of the rear collar certain parts being broken away and in section to show the mounted gripping-ring. Fig. 4 is a side elevation of the complete bearing it being removed from the casing and having portions broken away to show the bearing-sleeve and cage. Fig. 5 is a central sectional view, taken on line a-b 0f Fig. 4, but as having been given a turn relative to Figs. 1 and 2. Flg. 6 is a side elevation in detail of the bearing-sleeve, the solid line portions showing the improved groove, base and one of the perforated sections. Fig. 7 is a side elevation in detail of the bearing sleeve cage, the liange portion in section to show the oil ring device.

Fig. 31, a perspective detail view of the lock-ring portion.

For the purpose of simplicity I will divide up the description of the said journalbearing into the several heads, and describe them in the order named: casing and sleeve devices,lubricating devices and locking devices.l

Uasing and slee/ue devices-The bearing proper is provided with a suitable fixed outer casin A, which may be of any approved kin but preferred and shown in the drawin as having a fixed butremovable cap. ithin the said casing is mounted a revoluble sleeve B, as vindicated in Fig. 1, said sleeve being shown carrying a Bange B", that overhangs the front end of the casin A, and ermanently secured longitudinal y b l the ook-pin L, carried by the said casing` y registering against the annular shoulder on B at b. Near the base of the said shoulder are positioned and Vspaced a. plurality of in holes B extending radially inward t at are to receive the said lock-pin when itis desired to lock the sleeve B, circumferentially within the casing. The rear collar'D, is provided primarily to close the end of the casing, but it is formed in a. manner to be centrally located within the end of the sleeve B, and if desired it may be secured to the several`V cage bars directly'adgcent which will be described presently.

owever in the present instance it 1s secured to the casing h cap-screws D.

'The sleeve is preferably formed in equal longitudinal sections and is seem-abi;7 pinned together and secured bly screws B see FiV 17. The flanged en B of the sleeve i3, has ashallow annular recess B1 formed thereon, and a plurality of s aced apart-holes B', to receive the said loc -pin hereinafter described.

The interior of the mounted sleeve is nowA described. (The details relating to its interior construction have been shown and de scribed indetail, it being the subject mat` ter of` LettersPatent issued to me, Serial No. 1,109,642, September 1,1914.) Briefl stated, the conical interior of the sleeve is likewise provided with a central threaded portion and for the same purpose, but in my presentimprovement the sleeve B, is longitudinally fixed within the casing A, as shown. As previously mentioned I have added to the said sleeve a langedportion B, for the reason that it may be mounted within any suitable casing wherein the com plete bearing may be employed. l

Referring to Figs. 1,-2 and 17, I have shown a chamber A2 situated directly under the bearing and connected to this cl'imubcir is an auxiliary chamber A4, it being verti cally disposed, and by reason of its engaging hood portion A3 it completely encircles the rear end of the bearin Both chambers form an integral part o the casing, and their office will be described in turn.

Wear-compensating devices-The bearin lining proper C, is in the form of a cy indrical tube, it being of the proper di Vameter and len th (see Fi 19 and 21,) and havin a p urality of t iclrened Wedge portions formed radially on its cuter surface, and extending thereon its fu length. Between each of the said wedge portions is disposed a semi-circular tyrant` C2. and at the vertex of the same are die posed a series of perforations C, that ci; tend radially through the said reduced par tions of the bearing lining. At the vente f of the said perfor-ations a plurality of shui low connecting channels Cs, are fernuni, that connect each series of perforations into straight clearance channels, for a reason hereinafter described.

There are to be mounted over the 4severa?. Wedge portions P, of the said lining, a plurality of lobe like grids C', which precisely fill the circumferential space intermediate between each two longitudinal grooves C.

The said bearing-lining in the present instance is made in the form of a unit, and from any suitable bearing metal that may be die cast. However by the said process the lining if desired may be formed in icmw panion longitudinal sections, the parting to be made intermediate between the said wedge portions. As previously mentioned. said wedge portions positioned on the bearu ing-lining are formed in a manner to dovetail a plurality of rid portions C', which have been machine ormed and of the pro er length thereof. The said grids" have para le] side margins and a e preferably made of steel, in this form t ey are removably' securedv to the said lining by suitable screws P. The unit device is now inthe form to be reinforced by its accompanying cage ortion and together machine formed to their proper dimensions.

The bearing-sleeve formed in this Ina-n` ner provides a construction wherein not an ounce of dead weight lies on the supported journal. p

The inner surface or wall of the said device is unbroken, in order to provide means whereby a continuous ilmof oil may be retained therein, thereby reducing the objec tional co-eiiicient of friction to a minimum. I attain and maiutaiinthis most desirable result, by combining the following device. E is a cage it being provided to engage suplport and control the inner positioned bearing-sleeve device as described. Referring to les Figs 5 and 7, it consists of a plain ring or flange portion, which in the resent instance is preferred, but if desiredp it may be formed in companion or separable portions.

In the present instance, said flange has an annular clearance opening slightly larger than the journal to be carried, on the inner surface ofthe said flange is provided a reduced portion forming a groove E, as in Fig. l, and adjacent the said groove are positioned a plurality of spaced apart bars El and E, and in the present instance and preferably said bars are cast integral with the flange portion, but if desired they can be so formed and secured by other means permanently to the flange. In the present device there are four bars, to correspond to an equal number of right-angular flaring grooves positioned between the bearingsleeve grids C', said bars in the present instance being formed longer than the bearingsleeve to be sup orted, the purpose of which will be present y described, and of a form to precisely fit and slide into the already described grooves C4, disposed on the bearingsleeve. The said cage is now placed around the bearing-sleeve, and constitutes ractically one device, the cage bars occup ing the several spaces not filled by the bearingsleeve.

The said device is now machine formed in a manner to fit into the tapered sleeve B, as described. Threads are also formed on the longitudinal center portion of the said grids, in a manner to engage the companion threads, disposed Within the wall of the said sleeve. An eccentric recess is formed on the inner margin and extending outwardly on the face of the llange E, the purpose of which will. be hereinafter described.

The bearing-mechanism is now mounted Within the sleeve B, and by turning the cage E, the threaded portion of the said sleeve causes the bearing mechanism to be drawn within the flanged recess on B at B", which acts as a stop to fix the longitudinal position of the said cage. The lock screw E", carried by the flange B", is now adjusted within the groove E5, to secure .its position as described.

The rear stationary collar D, is noW placed inposition over the journal J, it being centered Within the end of the sleeve B, as be- -fore described by a projecting shoulder formed on its inner face, and securedto the casing by screws D2. The portion of the flange E that projects beyond the sleeve flange B, is formed in a manner lto apply a suitable Spanner. The bore of the bearingsleeve C is made a fraction larger than the -journal carried, and therefore by turningthe cage E slightly to the right with the Spanner, `radial adjustment of the bearingsleeve is provided by reason of the reduced portions C2, of the sleeve-lining at the said point bein compressed, and at the same time as beire mentioned the said bearingsleeve is drawn slightly backward by its thread engagement Within the reverse conical like sleeve, there being an annular space provided within the rear end of the said sleeve primarily for that purpose.

It is also evident that a reverse action of the Spanner will cause the said bearingsleeve to expand as it is caused to travel toward the front. It should be clear also that by locking the cage E, by lock-pin L, and releasing the casing lock at L, and by again applying the spanner as in the first instance, the complete bearing mechanism may be turned in either direction, thereby providing circumferential adjustment. Therefore it should be manifest that I have provided :L unitary bearing'construction absolutely substantial, but yielding to the means supplied for varying the inner diameter of its journal opening. Again referring to the bearing` sleeve grids, it should be understood that they saine are not intended to bc replaced as their oliice is only a supporting device for the said bearing lining, which after continued use may be removed and quickly replaced by an exact duplicate lining as shown, then`- by avoiding the loss of time and needless cxpense.

Lubricating (Zalamea-The oil chamber as has been mentioned is in fact the part of the casing not occupied by the bearing. The main oil settling chamber A2, carries a rib portion a, it being a necessary support for the above positioned sleeve B. The central portion of .said rib is removed to form a pa sage that communicates `vith a transv'ersoy annular passata A iformed in the casing thereof.

As heretofore mentioned thc open ends ol the sleeve B aril closed in a normal manner by removable attached collars D and E.

ln the present drawings two forms of oil ring devices are shown, and each form is applied in a position requiring their dissimi lar construction. Referring to Figs. l0, 1.1. and 12 .formed on the front face of the cage langeE, and extending radially from the journal opening, I have formed an eccen trie recess, into which are positioned a plurality of curved segment portions F2 and also the key l?, their inner sides engaging with the journal .l thereof.

The upper and lower ends of the said curved segments are slotted in order to en gage the web portions f and f. The webs are formed integral with the said key. connecting the uppermost ends of the device as shown. An annular recess is formed in the said ca e flange registering with the face of said oi -ring into which a ring flange E", is positioned and securely attached for the purpose required. :The said oil-ring is adjusted inths wayesi screw E4 is carried by the 4flange portion E, that engages with Vthe slot F, provided in the key therefore it is evident. that by tightening the said screw,

the worn surface of the oil-ring will allow` of the necessary contraction that Vis required. The ring segments are preferably formed of wood fiber. Mounted within the rear collar I), is shown a modified form of the oilring device, it comprises a plurality of o positely disposed cui-ved se ments G and (ii, mounted within a vertical y positioned oblong slot formed within the said collar opening, the said curved segments are mounted on suitable rod portions, that are slidably carried by the said collar. The said rod portions are reduced at their extreme ends G2, and carry a suitable spring G, that is in turn compressed by a screw nut G", which tends to force the said curved segments together in a manner to adjust the same when required. The reduced ends of the said segments are slotted in a manner to receive web-portions G as shown.

Referring to Fig. 4, an annular Space is shown projecting back, and adjacent the bearing-sleeve. Positioned in this space are a pair of spiral links H and H see Figs. 8 and 9. The said links are mounted spirally around the journal J, and are detachably attached at their one ends, to the projecting ends of the cage bars E, b suitable screws h, while their other ends o the said link are provided with spring portions h', and securably attached to the bearin sleeve. Ag indicated in the drawings, the sald links are attached in a manner to act in coiiperation with the revolving journal J.

The oiliee of the said device is this-as the oil is carried up by the journal,a much larger quantity is lifted by the exposed section of the journal than is carried elsewhere.

Therefore this eXtra volume (indicated by i the arrows) is thrown over toward the bearing-sleeve openings byV reason of contact with the links, and b gravity is filtered through the openings 5, mt'o the bearing as desired. The said links are formed from la suitable ductile alloy, that will readily conform to the curvature of the journal, andto these are secured a slidable base of leather.

It should be observed, that as the bearingsleeve travels back slightl by .reason of being adjusted radially, t e pitch of the links will be likewise decreased, hul'. prvision has been made in the length 'of the space for their operation, whereby no interference will need to occur. `It should be evi-` dent that in an cil tight chamber' as shown and described, a sulicient head of oil 1s carried and maintained, above the' lower linev of the journal. Therefore in the most simple manner the clean top portion of the' oil is distributed throughout the bearing without splash or agitation.

y In this mechanism I have in a great measure used only the elements that are otherwlse necessary, in their place, to'attain the desideratum,thereby reservin acontinuous ilm 0f oil in any undbstructe bearing surace.

The lock-pin device-This is considered as being an essential part of the invention, and the same is used as a means to prevent other, than the operator to disturb the adjustment of the bearing. The device may be used to lock the sleeve B, in its initial position also to lock the bearing-cage mechanism after it has been adjusted radially. To mount the lock-pin in its position, and to operate requires only a round h l' of a roper size to be formed in the part to be ocked. It consists of a round cylindrical sleeve, of which a portion, is a art of the reduced pin mounted within. o describe brieiy, (see 25 and 28 wherein isshown the main sleeve ortion K, which carries a slidable pin portion Le). The locking-ring K1 with its attached spring L, is mounted over the reduced end of the pin L".

The device now being complete, it is entered into the said casing. The lock-lugs K register within the slots KB, provided within the wall of the casing as indicated. A pin nipple L, is now placed over the reduced end of said pin, in a manner to secure both the nipple and spring. .The lock-pin is now complete;

To operate it should be seen that by placing the key K in its seat, the lock-ring may be turned slightlto the left, thereby releasing the said ook-ring. The key may then be turned in the opposite, direction, and thereby engage the portion L", releasing the said pm portion to be withdrawn. And by allowing the key to be carried back and removed the said spring will force the pin portion to returnin its former position.

I have claimed in previous applications those inventions and features of inventions whi'ch.are basic, and 'subsequently are shown and described unavoidably herein, but are not herein claimed.

Moreover it is manifest that the present invention in many of its devices is not limited to a fixed casing employed as a journal bearing, but can be employed in rious combinations and not depart from the spirit of the invention.

What I believe to be new and desire to secure by Letters Patent is 1. In a deviceof the character described, a support for a journal, a removable lining device disposed around the journal., a plu rality of devices disposed around the said removable lining in a manner to support the same, and adevice arranged to act to position and primarily support the said devices substantially as described.
